Abstract
In a file structure, it is possible to properly assist a user of a computer to operate a file without the use of an extension of the file and overcome some problems caused by the difference of the development time between an operating system and application programs in the computer. In the file structure, a file comprises file content information formed of a program code or data processed by the computer and a management program code performing processes for assisting the user to operate the file corresponding to the file content information. Unlike conventional file creation and display methods depending on the extension, it is possible to properly aid user's file operations such as a file selection by calling the management program code from the operating system. Since the management program code is called based on an interface uniformly prescribed for all files in the computer, it is possible to apply the management program code to the files independently of the difference of the development time between the operating system and the application programs in the computer.
